IMPROVEMENT IN HEATING AND VENTILATING STOVES Specification forming partof Letters Patent No. 182,529, dated September 26, 1876; applicationfiled February 17, 1876.

To all whom it may concern:

Be it known that I, CHARLES D. MOODY, a resident of the city and countyof St. Louis, State of Missouri, have invented a new and usefulImprovement in Heaters and Ventilators, of which the following is afull, clear, and exact description, reference being bad to the annexeddrawing, making part of this specification, in which- Figure l is acentral sectional elevation of the invention Fig. 2, a horizontalsection on the line X X of Fig. 1; and Fig. 3, a bottom view.

Like letters indicate like parts.

The present invention relates to an improved construction for heatingand ventilating a room or building. 7

Referring to the annexed drawing, A represents a heater or furnace ofany approved design. B represents whatI term a hot-air chamber. Itpartially surrounds the heater, or furnace, and, preferably the frontand sides thereof. 0 represents what I term the ventilating-chamber. Italso partially surrounds the heater, and, preferably, the back thereof.The two chambers abut upon each other, and, together, surround theheater, saving the needed space for openings thereto; and the twochambers are preferably formed by means of acasing, D, extending aroundthe heater, and at a suitable distance therefrom, and two partitions, c0, arranged vertically inside the casing, on either side of the backpart of the heater, and extending from the casing in to the wall of theheater. At the bottom the ventilating-chamber is open to the room orbuilding, and at the top the chamber is provided with aventilating-shaft leading to the open air outside the apartment orbuilding, and, preferably, by connecting it with the ordinary smoke-pipea of the heater. The hot-air chamber at its bottom is closed to theapartment or building, but at that point is, by means of the openings 12b 11, provided with a communication with the open air outside theapartment or building. At its top the hotair chamber is provided withopenings leading to the apartment or building that is being heated andventilated. E represents the base of the construction; F, the door orpassageway to the heater, and G represents the ashpit.

The operation of the invention is as follows: Let the improvement belocated in the apartment that is being warmed and ventilated. Theheater, in such case, is p eferably arranged with its base E restingdirectly upon the floor of the apartment. The heater is fired in theusual way, and through the door F. Air from without the apartment isdrawn into the hot-air chamber through the openings b b b, 850., whereit is heated, and then, through the openings 1) b b, &c., in the top ofthe chamber, it is delivered into the apartment. At the same time theventilatingchamber, from beingin close proximity to the heater, isheated. This induces a current from the apartment, which, entering theventilating-chamber through the openings 0, &c., at

its bottom, is caused to rise to be delivered through theventilating-shaft c to the open air outside the apartment. In thismanner the apartment is not only warmed, but, in. addition, there is aconstant supply of fresh air and a constant discharge of foul air. Whenthe improvement is located without the apartment or apartments to bewarmed and ventilated, suitable connections are made by which pure airfrom without the building or apartment can be delivered to the hot-airchamber, and by which, after being heated,

thehot-air can be delivered into the apartment or apartments; and alsoconnections by which the foul air from the apartment or apartments canbe delivered to the ventilating-chamber.

I am aware that heretofore a heater has been surrounded with a hot-airchamber, and the hot-air chamber, in turn, by a ventilatingchamber; butsuch a construction is more expensive, bulky, and complicated than theone above described, and, in consequence of the ventilating-chamberbeing removed from. the heater, the ventilation is not so thorough andsure. I am also aware that systems of tubes by which fresh air fromwithout is discharged into the apartment, and the foul air of theapartment is withdrawn therefrom and discharged into the chimney, havebeen combined with a heater. But such tubes, either singly or-jointly,do not surround the heater, or even the principal portion thereof; nordo they abut upon each other, as in the case of the heating-chamber andventilating-chamber in the present construction.

What I claim is- The combination of the heater A, hot-air chamber 13,ventilating-chamber O, openings 1) b, b b,&c., a", shaft 0, and pipe, a,substantially as described.
